Institute of Nuclear Power Operations


  • Japan’s nuclear utilities and vendors have created a new group called the Japan Nuclear Safety Institute (JANSI), which the Federation of Electric Power Companies of Japan said is modeled on the U.S. Institute of Nuclear Power Operations and the World Association of Nuclear Operators. Makoto Yagi, FEPC’s chairman and president of Kansai Electric Power Co., said last week JANSI was created to further improve nuclear power plant safety and to “ensure the completeness of severe accident management measures based on lessons learned from the Fukushima accident.” Yagi said that JANSI, like INPO, will give utility executives advice and recommendations on operations. The agency will seek guidance and peer review from both INPO and WANO. JANSI’s membership will comprise 123 companies, Yagi added.

Plant Update

  • Tokyo Electric Power Co. has removed the primary containment vessel dome from Fukushima Daiichi reactor 4. TEPCO published photos and video clips showing the dome being lowered to the ground. The dome will be cut up and stored on site. The company also is preparing to remove the reactor pressure vessel head in October. Steve Kraft, NEI’s senior director for Fukushima response, said these actions are key steps to prepare for the installation of a structure over the building that will allow fuel to be removed from the reactor’s used fuel storage pool. Last week TEPCO also attempted to use a camera-equipped balloon probe to investigate the condition of reactor 1’s refueling floor. The initial attempt was unsuccessful, and the company said it will try again.
